最近的研究发现，年龄与解码情感面部表情的准确性呈负相关;年龄的这种影响对演员和评分员都有影响。鉴于动机差异和刻板印象可能会偏向情绪的归因，本研究的目的是探讨这些年龄效应是否是由于反应偏见，即反应类别的不平衡使用。30名年轻的评分员（19-30岁）和30名年长的评分员（65-81岁）观看了代表相同年龄范围的年轻和年长演员的视频剪辑，并解码了他们的面部表情。我们计算了原始命中率和偏差校正命中率，以评估潜在的年龄相关的反应偏差对解码准确性的影响。虽然原始命中率表明演员和评分员的年龄对悲伤的解码准确性有显着影响，但当反应偏差被纠正时，这些年龄影响不再显着。我们的研究结果表明，年龄对解码面部表情的准确性的影响可能是由于，至少在一定程度上，与年龄相关的反应偏见。
Recent studies have found that age is negatively associated with the accuracy of decoding emotional facial expressions; this effect of age was found for actors as well as for raters. Given that motivational differences and stereotypes may bias the attribution of emotion, the aim of the present study was to explore whether these age effects are due to response bias, that is, the unbalanced use of response categories. Thirty younger raters (19–30 years) and thirty older raters (65–81 years) viewed video clips of younger and older actors representing the same age ranges, and decoded their facial expressions. We computed both raw hit rates and bias-corrected hit rates to assess the influence of potential age-related response bias on decoding accuracy. Whereas raw hit rates indicated significant effects of both the actors’ and the raters’ ages on decoding accuracy for sadness, these age effects were no longer significant when response bias was corrected. Our results suggest that age effects on the accuracy of decoding facial expressions may be due, at least in part, to age-related response bias.
